Re: [algogeeks] seperate diff types of coins
Minimum no. weighings: Divide 8 coins in group of 3, 3 and 2. For minimum weighsing group1 's total weight is x units(say) --FIrst weighing Groups 2nd total weights is y units Second weighing. Lastly one more weighing among a unit and b unit coins.---3 rd weighing So minimum 3 weighing is required.

@navin...Sorry didnt get you how come u were able to segregate all the coins by the proposed method??

Re: [algogeeks] seperate diff types of coins
Let we have 8 coins named (for simplicity) x1, x2, x3, y1, y2, y3, a, b According to your question 3 of them weigh x units : x1+x2+x3 =x 3 of them weigh y units: y1+y2+y3 =y now consider the case when i grouped (x1, x2 x3) in single group (y1,y2 ,y3) in one group and (a,b) in one group. Now we will measure weight of 1st group (x1, x2, x3) :It will give x then we conclude that all elements in this group are those element whose total weight is x :Type 1 element. similarly for y. and for the last group we will pick up any element and measure its weight ..its weight will be either a or b. Depending upon outcome we will categorize them a and b. So 3 weighing is required.
